Information on how many people won an appeal against the withdrawal of their (a) disability living allowance and (b) personal independence payment at a tribunal in 2017 is not held centrally.
HM Courts & Tribunals Service (HMCTS) collects data on various types of issue that may be disputed in an appeal before the First-tier Tribunal (Social Security and Child Support) (SSCS). These include entitlement to, or rate of payment of, a particular benefit. However, the issue specified in Question 130495 (and 132503) - “withdrawal” of disability living allowance or personal independence payment - is not included in the list of categories recorded. HMCTS does not, therefore, hold the information requested.
Information about the volumes and outcomes of appeals to the SSCS tribunal is published at: www.gov.uk/government/collections/tribunals-statistics.
